Method and system for electronically storing data on a document

Abstract

A method of recording data in a data storage medium affixed to a document, the document having a document ID printed thereon and the data storage medium having the document ID stored therein, the method comprising capturing data written onto the document by means of a digital pen, the digital pen having an imaging system, determining, by means of the imaging system of the digital pen, the document ID printed on the document; comparing the document ID determined by the digital pen with the document ID stored in the data storage medium and on if there is a match transferring the captured data from the digital pen to the data storage medium.

1 . A method of recording data in a data storage medium affixed to a document, the document having a document ID printed thereon and the data storage medium having the document ID stored therein, the method comprising: 
 capturing data written onto the document by means of a digital pen, the digital pen having an imaging system;    determining, by means of the imaging system of the digital pen, the document ID printed on the document;    reading the document ID stored in the data storage medium; and    comparing the document ID determined by the digital pen with the document ID stored in the data storage medium and if there is a match transferring the captured data from the digital pen to the data storage medium.    
   
   
       2 . The method of  claim 1 , wherein prior to reading the document ID stored in the data storage medium, the digital pen is placed within a predetermined distance from the data storage medium.  
   
   
       3 . The method of  claim 2 , wherein the predetermined distance is  5 mm.  
   
   
       4 . The method of  claim 2  or  3 , wherein the document ID is located on the document within the predetermined distance from the data storage medium.  
   
   
       5 . The method of any preceding claim, wherein the document ID comprises a data item uniquely identifying the document.  
   
   
       6 . The method of any preceding claim wherein the document ID is in an encoded format.  
   
   
       7 . The method of any preceding claim, wherein the document ID is located on the document at a plurality of places.  
   
   
       8 . A system for recording data in a data storage medium affixed to a document, the system comprising: 
 a document having a document ID printed thereon;    a data storage medium affixed to the document and having the document ID stored therein; and    a digital pen having an imaging system arranged to determine the document ID printed on the document and capture data written on the document by the digital pen, a transceiver for transferring data between the data storage medium and the digital pen and a processor arranged to compare the document ID printed on the document and the document ID stored in the data storage medium and to further enable transfer of the captured data from the digital pen to the data storage medium only if the determined document ID and stored document ID match.    
   
   
       9 . The system of  claim 8 , wherein the data storage medium comprises an RFID tag and the digital pen transceiver comprises an RF antenna having a predetermined maximum operating range.  
   
   
       10 . The system of  claim 9 , wherein the predetermined maximum operating range is 5 mm.  
   
   
       11 . The system of  claim 8  or  9 , wherein the digital pen imaging system includes an image sensor having a predetermined field of view and the document ID printed on the document is at a location such that when the RF antenna is within the operating range the document ID is within the field of view of the imaging sensor.  
   
   
       12 . The system of any one of  claims 8  to  11 , wherein the document ID uniquely identifies the document.  
   
   
       13 . The system of any one of  claims 8  to  12 , wherein the printed document ID is encoded.
